The grill connects the entire foundation to the single structure and thus contributes to an even distribution of the weight of the house and all the piles.
Most of the time, this foundation is organized as a monolithic reinforced concrete structure. The resistance is provided by the metallic structure (steel foundation for grilling).
Minimum clearance of around 800 mm (8cm) is provided between the grillage beams so the concrete will be easily poured and properly compacted.
As the concrete filling doesn’t carry a load, it functions to keep the beams in position and prevents them from getting corroded.
The depth of concrete below the lower tier is kept at a minimum of 150mm (15cm).
First, for the solid monolithic grid, we need to produce and install the structure. We prefer this barbecue because it is more reliable.
The formwork is made of edge boards in the form of rectangular gutters. Its height is 1 foot and width is equal to the minimum thickness of the house wall. A space of about 15 to 30 cm should be defined between each grid.
Within the formwork, we have to define a reinforcement connection structure using the connecting wire. The shortest distance from the structure next to the formwork must be the same.
Then, the reinforcement is connected to the same connecting wire used previously.
Then, the concrete must be prepared with the cement mixer. It is poured into the formwork in a continuous cycle. The connections must be placed at a height of about 25 to 30 mm so that they are completely immersed in the concrete. Concrete must be poured with care to avoid unwanted cavities. 6. After filling the surface, it should be leveled and left to dry. When dry, the formwork can be removed. The foundation is ready now.
First, a trench is excavated of depth 90 to 150 cm and levelled. A layer of concrete ratio 1:2:4 or 1:1.5:3 of thickness 23 to 30 cm is spread and compacted.
Over this concrete base, steel I-beams are laid and placed at suitable intervals 45 to 90 cm. This I-beams length is equal to the foundation’s width.
Then concrete is poured to fill the space between the I beams. Above these, the next layer of I-beams is installed perpendicular to the primary layer.
Again concrete is poured into the internal space to fill it.
Now fix steel stanchions by connecting with the base plate. A gusset plate and side angles are used for a secure connection. To make them monolithic, these connections are also secured in the concrete.
